    hello

    i like to try to build a motion platform, maybe shoot for a hex like 6dof.
    but i am in an apartment with 3 circuits ( 2x 15amp living/bedroom and 1x 20amp kitchen)

    can i ask you guys what are you motion rig specs?
    a) how many DoF,
    b) how many Motors,
    c) how many power supply with ratings / watts..

    im just wondering your opinion as if i was going to build one at home, is 6 doF feasible.. i might want to even build 2x 6doF platforms..

    thanks!

    My Motion Simulator:
    6DOF
    6DOF linear actuators (build thread at: https://www.xsimulator.net/community/threads/flypt-6dof-brushless-diy-actuators.10799/)

    Motors:
    6 DB59 Nanotec BLDC 24V motors with:
    6 poles / 3 phases
    Current 13.6A rated 40A peak
    Speed 3500 rated 4500 no load
    Power 220W rated
    Torque 0.6Nm rated 1.8Nm peak

    Drives:
    BLDC 8015 A for sensored BLDC motors with Speed and direction control

    Interface:
    Two ESP32 boards that count steps from the hall sensors on the motors, so no need for pots/encoders.

    Power supply:
    One Mean Well RSP-3000-24 (should be two).
    Outputs 24V, 125A, 3000W. Most expensive part of my rig.

    Resulting specs:
    For a 1605 ball screw (16 mm diameter and 5 mm per turn) I get:
    Tested up to 75 kg in one actuator.
    In theory, maximum rated speed of actuator up to 291 mm/s.
    Resolution of 18 steps per revolution or 0.277 mm.
